Abstract

Apparatus is disclosed for controlling die heads of screw-making presses having movable dies comprising a die head rotatably mounted on a shaft and having two dies, and a pivotally mounted controlling fork with a cam surface engaging the die head by rollers. The sections of the cam surface nearest to the pivotal axis of the fork are circular arcs centred on the pivotal axis while those sections of the fork which are farther from the pivotal axis and which engage the rollers are shaped as curves the distance of which increased from the pivotal axis in the direction of the working movement of the rollers. The circular arcs and the farther sections are connected by transitional sections.
